To all whom it may concern:

Be it known that I, NILs H. ANDERSON, a citizen of the United States,residing at Middletown, in the county of Middlesex and State ofConnecticut, have invented certain new and useful Improvements inType-Writing Machines, of which the following is a full, clear, andexact description, such as will enable others skilled in the art towhich it appertains to make and use the same.

This invention relates to typewriting machines, and with regard tocertain more dominant features thereof, to type actions therefor.

One of the objects of the present invention is to provide a type actionwhich will be sim- 1e and practical inconstruction, and durale andeflicient in action. Another object is to provide a type action of theabove character which will be peculiarly applicable to silentlyoperating machines. Another object is to provide practical means for somounting the parts as to enhance their case of movement and reduce wear.Other objects will be in part obvious and in part' pointed outhereinafter.

The invention accordingly consists in the features of construction,combinations of elements and arrangement of parts which will. beexemplified in the construction hereinaftenset forth, and the scope ofthe application of which will be indicated in the following claims.

In the accompanying drawings, wherein is shown one of various possibleembodiments of this invention, v

Figure 1 is a side elevation of a complete type action in normalposition, and such other parts of the machine as are necessary to showan application of the present in- Figs. 6 and 7 are enlarged views takenat right angles to each other of certain details.

Similar reference characters refer tosimilar parts throughout thedifferent views of the drawings.

Referring now in detail to the accompanying drawings and moreparticularly to Fig.

Specification of Letters Patent.

1, which shows such parts of a complete typewritmg machine as arenecessary to obtam a clear understanding of the present in- The keylevers are pivoted at their rear ends upon a fulcrum bar 6 and heldupward there'- against by return springs 7 adjustably mounted in asuitable support'8 in the frame of the machine. The type carrier isactuated from the key-lever 7 through the instrumentality of deviceshereinafter more specifically described, although it may here be statedthat intermediate each type carrier and its key lever is a system oflinkage, adapted to move the type carrier to perform its functions bypressure in contradistinction to impact, thereby to effect the printingoperation in a silent and noiseless manner.

The type carriers 4 are radially disposed with relation to the printingpoint, as shown more clearly in Fig. 4, and are mounted to slide backand forth between upper and lower guide plates 9 and 10, respectively.The lower guide plate 10 is provided, at its rearward part, with aplurality of concentrically disposed grooves 11 to collect any particleswhich may fall thereon whenmaking erasures, and prevent the same frominterfering with the free back and forth movement of the type carriers.These grooves also lessen the area of contact between the adjacentsurfaces and thereby render the movement of the type carrier easier.

. Application filed May 27, 1912. Serial-No. 659,867.

' vention, there is indicated at l a cylindrical ill : the type carrierin its movement toward the stamped from sheet metal, are pivoted at 1 1to the opposite sides of eaclrtype carrier. The opposite ends of theselinks arepivotally connected at with a second pair or links 16, whichin. turn are pivotally connected at their opposite ends 17 to theopposite sides of a relatively fixed block 18' mounted'on the frame ofthe machine. The links 13 andltl together constitute a toggle whichpositively limits the throw of printing lane, or platen.

The lin lrs 16 are provided, near their cen tral part, with offset lugs19', between the ends 20 of which is pivotaily connected. a single linkThe opposite end .of this link is in turn pivotally connected, at 22,hetwecir. the longer arms 23 of a pair of ele- 'jments such as bellcranklevers which are exception of link 21 arranged in pairs, as

shown more clearly in Fig. 5. This arrangement not only increases thestrength of the mechanism to withstand the'powerlul pres sure exerted onthepaper, but also provides a more even movement free from binding attheir points of pivotal connection. To avoid confusion, these pairs oflinks will be considered asheing single elements. It is thus seen thaton depressing the key levers the poll wire 28 and the link 27 connected.therewith will cause the bell ,c'rank lever to swing about. its pivot 21 toward the position shown in Fig. 2. The movement of the hell cranklever will, through, the connect ing link 21, tend to straighten thetoggle lorinedby thelinks 16 and 13, thereby moving the type carriertoward'the printing position.

As thelimited movement of the type can rier 43 on printing actuation ofthe key-lever is positively controlled by the straightening of thetoggle formed by the links 13 and 16, thev strength of impression may beaccu ratelyadjusted by moving the point 17, atwhich the link 16 ispivoted, toward and from the printing point, or plane. This maybeconveniently done by mounting the block-.18 in a radially disposedgroove 29 (see Fig. 4) on the front wall of the machine. The forwardpart'io't the block is provided with a notch 30 engaged bya col' lar 31on a threaded adjusting screw 321cm gaging a threaded openingln theframe.

lit will thus be seen that as the screw 32 is rotated, the block 18 willhe moved. back or forth relatively to the printing point. In ordertohold the block 18in adjusted position, a set-screw 33 engages a tappedout hole between each adjacent pair of type actions, and is providedwith a relatively large washer 34 adapted to engage the upper surface ofthe blocks 18, as clearly shown in Fig. 1.

As noiseless or silently operating xnachines perform the printingoperation by pressure in contradistinction to impact, the time actuallyused: in making the impression may be longerthan that requiredin impactmachines. In order to avoid. tendency to blur during the actual printingOperation and for other reasons, it is desir-' able to provide, in thetype action, prefer- I ably in the intermediate mechanism. be tween thetype carrier and the key lever, means which .will accelerate the actualprinting operation and withdraw the type from the surface of the paper,or printing plane before the escapement has time, to permit movementotthe carriage.

order to accomplish this result an gain other advantages there isprovided weighted member 35, the same being 'prelc erably comprised inor mounted on a link 21, and slightly ofiset with relation. to theknuckle of the toggle formed by link 21 and arm 23. The weighted member35 is also slightly offset relatwe to the longitudinal axis of the link21. This weight, under the normal operation of the device, as bvprinting actuation of the key lever, will acquire a certain momentum,which momentum will operate to carry the weight rearwardly, or towardthe printing plane, after keylever 5 has been arrested in its downwardor printing actuation movement by a'stop 3d,

the latter being positioned to arrest the printing actuation of thekey-lever prior to printing impression. Thus after the downward movementof the key-lever is arrested by the stop 36 the momentuni'of the weightis expended to force the type carrier toward the printing plane from apoint adjacent said plane, and thus also the toggle formed "by the links13 and 16 will be straightened.

Hence it will be seen that "the momentum of According to a well knownprinciple of mechanics, as'the links of the toggle assume ment of theends of the links decreases in speed and the pressure exerted thereby ismultiplied; consequently the type carrier ne carrier toward theprintingplane .a straightened position, the relative-moverested,afterwhich its momentum carries it into the posltion shown in Fig. 3, inwhich position the printing is concluded. Thus the momentum of theweight 35 is converted into straight line pressure ofthe type by theintermediate mechanism. When in final position. the link 21 and arms 23of ,the bell crank lever are also in a straight line, and in themselvesform a second toggle which not only increases the pressure exerted bythe type carrier, but also limits the movements of the movable parts.

In order to assist in urging the type carrier away from the printingplane and to completely restore the parts to normal position, there isprovided between the pivot point 26 and the upper part of the adjustingblock 18 a spiral spring 37 which exerts an upward pull upon theshortarm of the bell crank lever. The restoring movement, however, is notentirely confined to the spring 37, for the parts forming the bell cranklever being made of resilient sheet metal possess more or lessflexibility. Thus, as the momentum accumulator moves rearward into theposition shown in Fig. 3, where it is arrested, there will be a certainrebound, materially aided by a felt stop in member 51, hereinafte1described,to carry the toggles out of their straightened position and.thus withdraw the type from the surface of the paper. In other words,the key lever may be held down and the type will perform their functionand move a sutiicient distance away from the platen to eliminate ablurring or second impression, due to a second and opposite rebound, andto permit other type to be moved toward the printing point withoutaffecting the subsequent. operation of the machine.

At this point it may be noted that the weight35 has a certain turningmovement about the pivot point 22 asthe key lever is depressed. Theforcethus exerted 1s very slight at first, but as the action approachesthe positions shown in Figs. 2 and there is a very decided tendency forthe weight to turn about the pivot 22. thereby assisting in thestraightening of the toggles, This force may be increased by lengtheningthe dis tance from the center of the .weight to the point 22. After thebell rank lever has been brought to rest, there is a reverse forcebrought into. play to break the toggles due in part to the reversal ofthis condition. There is thus produced in this type of action a reallive force due in part to the momentum of the weight '35 which is verydifferent in "lever after the latter reaches its limit ofdownward-Jmovement. This is accomplished by permitting relative motionbetween power transmitting portions of said actuating mechanism, and inthe present embodiment by providing a pair of bent-in ears or powertransmitting portions 38 on the ends of the two parts C011$tltlltil1gthe bell crank lever, which ears respectively engage a certain, or powertransmitting portion, of the two parts forming the curved link 27,thereby providing a loose connection, or lost motion device, in saidactuating mechanism, the power transmitting portions or ears 38 beingmovable into and out of engagement with the power transmitting portionsof the link 27. The spring 37 assists in moving said portions intoengagement. Thus, as the bell crank lever is actuated on depression ofthe key lever-and is subsequently acted upon by the momentumaccumulator, the ears 38 will then move out of engagement with the underside of the link 27. In this manner the key lever may be held down toits limit of movement and the type carrier will complete its path oftravel to effect the printing free fromthe direct impulse of thekey-lever and.

fere with the rapid repetition of any single character or require acomplete return of the key lever to normal position under suchconditions of operation.

In 'order that the .universalbar mechanism which controls the escapementn1echa= nism, not herein shown, will be unaffected in its cycle ofoperation by the length of time during which the key lever may beinadvertently held in downward position, it is desirable to place theuniversal bar, indirated at39, in operative relation to the intermediatemechanism between the key lever and the type action. This universal bar.which is in the form of an arc concentric to the type carriers, extendsfrom one side of the machine to the other and in the path of travel ofthe cars 38 on the bell crank lever and 'at a suflicient distancetherebelow to be actuated only during the movement of the bell cranklever from the position shown in Fig. 2 to that shown in Fig. 3, orwhile the till tilt

and i8, respectively. These stops momentum accumulator is actingindependently or the operation of the key lever, and thepowertransmitting portions of the l1nk 2'3 and the 38 are moving fromeach other.

I ihis universal bar 39 is supported upon two upright members 4.0 atopposite sides of the center of the machine, only one of which is hereinshown, due to the sectional view. These 1 :mbersfill are pivotally.connected with horizontally disposed links it and pivoted at &3 and a l,respectively, on dependirig brackets 45. This parallelogram constructionprovides a vertical movement for the members 4-0 and consequently anequal vertical movement of all of the portions of the universal bar 39mounted the on. it the links 41-}. alone were used they would have asimple pivotal movement about their point of support, so that theforward end of the universal har would travel I through agreater arethan the rear end.

Secured to the front part of the universal her is a forwardly projectingmember all adapted to engage upper and lower stops l? are adjustablymounted on a depending bracket 49 secured, by means of a screw 50, tothe front wall of the i'rame oi" the machine to limit the up and downmovement of the car.

Coucentrically disposed with relation to the universal bar is mounted astop member 51 provided with a felt cushion. This stop is supported fromthe frame of the machine in any desired manner, and is adapted to takeup the shock exerted by the momentum accumulator in its rearwardmovement. stop'also prevents overthrow of the toggles and allows for theresiliency of the hell crank lever to return the parts to normalposition with the aid of the spring 3'2. It will be seen from Fig. 6that as the hell crank lever swings rearward, the ears 88 willcoact withthe universal her and actuate the same before heinghrought to rest bythe fixed stop, In this manner a much lighter and more delicatel actinguniversal bar mechanism may he employed than would otherwise he requiito withstand the strains exerted by the type action.

Members and 53 are parts or and connectcd with the line lock mechanismand escapement mechanism, respectively. .These mechanisms form nopart ofthe present in vention, except in so far as they may enter into certaincombinations, and therefore it is believed to be unnecessary to show thesame or go into a detailed description of their operation. It issuflicient to state that the member 52 has an oscillating movement with.

each actuation of the universal bar and may coact with a stop to'preventthis oscillation,

, when the. stop is moved into the path of oscillation as the carriagereaches a prede- The intermediate mechanism ot' tially as follows:Whenthe key lever 5 is depressed, the pull wire 28 will have a downwardmovement which in turn will cause the curved link 27 to move in the samedirection. Due to the formation of the cadet" the. hell crank lever asshown more clearly in Figs. 6

and 7, this downward movement will cause the bell crank to swing aboutits pivot point 24:, thereby tensioning the spring 37 and causing theupper part of the bell crank lever to swing rearward toward the platen.This rearward movement at first exerts a straight horizontal thrust onthe link 21 which isconnected at its opposite end with the lug 19 on thelink 16 of the toggle. he tween the adjusting block 18 and the typecarrier. As the downward movement of the key lever continues, themechanism assumes the position shown in 2, the lint: 2i. instead ofbeing thrust rearward is then being thrust downward, therebyto-straighten the toggle formed by the links 13 and 15,- at the sametime straightening the toggle formed by the'links 2i and While thesetoggles are being straightened it is, of course, to he understood thatthe weight 35, carried by the link 21 and off-set with relation to thelongitudinal axis thereof, is being swung upward and rearward, having acompound movement about the pivot point 2st and also the fifiutlilgpivot point 20.

The momentum acquired by the movement of the weight in this mannerconstantly increases, for it will he noted that the eiiective radius,that is, the distance between. the

applied to the key lever in operation and subsequentl delivers theenergy to the type carrier to perform its printing function after themovement of the key lever has been arrested by the stop 36.

Thus

lldti gas Not only is the momentum in reased due to the increase of theefi'ective adios of the momentum accumulator, but it is alsomultiplied'by the toggle arrangement of linkage. While the degree ofimpression is regulated to a certain extent according to the length ofthrow of the type carrier by the adjustment of the block 18, thestriking of a key lever with a greater force, as when making a pluralityof carbon -copies, will be multiplied to some extent in an action ofthis kind, for the momentum of the momentum accumu'lator will increase"according to the speed or force with which thekey is struck.

3'0 ment of the type action that the universal of contact with the stop51 independently ated thereby, a platen, means to positively limit theextent of the printing stroke of- As the momentum accumulator is free tokey lever has been arrested in its downward movement, due to the looseconnection between the bell crank lever and the link 27, it will swingrearward to the position shown in Fig. 3, thus straightening both setsof toggles and efi'ecting the printing in a rapid and noiseless mannerand with great pressure.

Its rearward movement will be stopped by two means, the coaction of thetype with the platen and the coaction of the bent-in ears 38 with thestop member 51' mounted on the frame of the machine.

Immediately after being arrested, the resiliency of the arms 23 and thestop bar cushion will cause a slight rebound suflicientto break thetoggles-and thus carry the type out of contact with the paper. If thekey lever is released immediately after being struck, as occurs in thenormal operation of the machine, the spring 37 will return the parts tonormal position.

A pad 54 mounted on the front-wall of the machine will cushion thereturn movement of the momentum accumulator 35, thus noiselesslyarresting the movement of the movable parts. I

It is during the last'part of the moveher is actuated, that is, when theparts are moving from the position shown in- Fig. 2 to that shown inFig. 3. By reference to Fig-6, it will be noted that the bent-in ears 38contact with the universal bar 39 and press the samedownward untilarrestedby thestop 51. As the ears 38 are raisedout of the release ofthe key lever the universal bar is permitted to return to normalposition, thus completing its cycle of operation whereby the 'escapementmechanism connected therewith through the link 53 may really be said tooperate to space the scar riage during the depression of the key lever,that is, while the key-lever is at the limit of its printing stroke, forit is quite clear that even if one key lever is held down, otherkeylevers may be operated indefi nitely.

Thus the means for actuating the escape ment is operable independentlyof the return movement of the key-lever.

It is thus "seen that this invention provides a simple and practicaltype action adapted to effect the printing operation in a rapid andnoiseless manner, and accomplishes, among others, all of the objects andadvantages above set forth.

As many changes could be made in the above construction and manyapparently widely different embodiments of this invention could-be madewithout departing from the scope thereof, it is intended that all mattercontained in the above description or shown in the accompanying drawingsshall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the followingclaims. is in-' tended to cover all of the generic and specific featuresof the invention herein de-' scribed and all statements of the scope ofthe invention, which, as a matter of langua e, might be said to falltherebetween.
